F fieldbus
OUNDATION
A specific fieldbus technology developed and supported by Emerson Process
Management and the other members of the independent Fieldbus
Foundation. F fieldbus technology uses device descriptions and
OUNDATION
function blocks to enable intelligent field devices to execute control functions
traditionally performed by a distributed control system.
Graphics
A feature that enables the 375 Field Communicator to display device
information as images, charts, and graphs. The Graphics feature utilizes
enhanced Electronic Device Description Language, EDDL. To view the
graphical representations, you need a device with enhanced EDDL, a 375
Field Communicator with a Graphics license, and the 375 system software
version 2.0. If the 375 Field Communicator does not have a Graphics license,
enhanced DDs can still be used. However, the graphical representations will
not be displayed.
HART device
A device that communicates information using the HART protocol.
